Uncollected post

hi,

we live in a neubau apartment and as people were moving in and hadn't put their names on the post boxes the post man just left any mail that didn't have a matching name on top of the boxes...

fair enough... most of it was collected...

now, a year later there are still a number of letters and packages hanging around that nobody has collected... they are bugging me and i'm planning to stick them back in the mailbox with 'recipient not known' or something written on them...

what might the appropriate term/phrase auf deutsch be?

unbekannt verzogen
i think

stimmt...

danke...

stop worrying about inconsequential shyte and A)...ignore them
...post them next door
C) ...burn em
D)...get a friggin grip

Take it all, open it, scope it for good stuff like Credit Cards, bank card PINS, etc. etc. then bin the useless bit in a paper recycling bin far away
